The Hoya 49mm HMC 81C Light Balancing Filter is uniform in color and with a mired shift value of +35, can be applied to purposely create a warm cast over an entire image. This effect can be obtained under daylight when this filter is used on a film camera system with daylight film installed, or on a digital camera system with its daylight white balance setting selected. The Hoya 49mm HMC 81C Light Balancing Filter is also useful for balancing light sources with a color temperature of 3600K for type B tungsten film, which is designed to accurately reproduce colors under 3200K light sources.

The greater the difference between the color temperatures they are designed to correct for over 3200K, light balancing filters for type B tungsten film are considered to be progressively stronger in their effect when used to add warmth to a daylight image.

This filter is constructed from optical glass for increased clarity and color fidelity. Its aluminum-alloy filter ring is durable while remaining lightweight. To prevent internal ghosting and reflections, each glass surface includes three layers of anti-reflection coating. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.

When used, the Hoya 49mm HMC 81C Light Balancing Filter's 0.15 density darkens the entire image by 0.5 stops. This reduction in exposure can be compensated for by adjusting the aperture setting of the lens it is placed on, or the shutter speed of the camera being used.
